Abstract
A system providing a framework for the negotiation of a dual-channel communication protocol between modems connected by a communications link. The dual-channel communications link includes a data channel used for sending and receiving data or code and a command channel for sending and receiving command and status information. Enhanced capabilities include providing that data on the data channel may be compressed using one of a plurality of compression algorithms, data may also be encrypted using one of a plurality of encryption algorithms. Additionally, LCP spoofing is provided as a way to reduce the time required to establish PPP links.
